I haven’t had any multiple monitor problems since switching to KDE that weren’t actually Nvidia driver issues. My “TV” is a third monitor on a long ass HDMI cable.
The only issue I can still think of on KDE with Wayland is that fullscreen games tend to crash when switching on/off a monitor during gameplay.
Not the end of the world but it seems like something that could be avoided.
My only remaining issue is that wayland has slightly more input latency when playing games, enough that it’s noticeable (or a very convincing placebo effect).
This makes it so that I have to use X11 and that I have to disable compositioning when playing games as my displays have different refresh rates. All in all, not a big problem but looking forward to be on wayland for good soon.
